Specification of Letters Patent.

' Patented Aug.5, 1919.

Application filed September 16,1916. Serial No. 120,508;

To all whom it may concern:

Be it known that I, JOHN GEHRINGER, a citizen of the United States, residing at Ann Arbor, in the county of Washtenaw and State of Michigan, have invented certain new and useful Improvements in Weed-EX- terminators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in that type of weed exterminator, 0r destroyer, consistlng of a reservoir for holding a quantity of poisoning liquid, and having the lower end thereof provided with a discharge nozzle and a spring pressed valve for controlling communication between the nozzle and the reservoir, and adapted to be unseated when the valve stem contacts with the ground, and an object of the invention is to improve the construction of the nozzle so that it can be conveniently attached or de tached from the reservoir and of such construction that the discharge end thereof can be inserted into the ground during discharge of liquid therefrom, so as to prevent splashin of the liquid when being discharged.

ther objects will appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had to the accompanying drawings forming a part thereof, in

which:

Figure 1 is a vertical elevation of the exterminator device, showing the improved nozzle associated therewith,

h ig. 2 is a vertical detail elevation, taken through the lower end of the reservoir and through the nozzle, and

Fig. 3 is a side elevation ofthe nozzle detached from the reservoir.

Referring to the drawings in dwhil, the numeral 1 designates a reservoir formed of a downwardly tapering tube and having the lower end of the walls thereof deflected inwardly, as shown at 2, and threaded, as at 3. Detachably connected with the lower end of the reservoir is a nozzle consisting of a discharge spout 4, being of a uniform diameter throughout its length, and a flanged cap 5, that has the inner surface of the sides thereof threaded for threaded engagement with the threads 3 on the deflected portion a at the lower end of the reservoir 1.

"Operable through the reservoir 1 and the dlscharge spout of the nozzle is a stem 7, which has its lower end extended through the spout 4 and has the lower end thereof terminally extended beyond the free end of the spout 4:, as shown more particularly in Fig. 2 of the drawings. A cylindrical shaped valve 8 is carried by the stem 7 and normally cuts off communication between the interior of the reservoir 1 and the discharge spout 4. A coil spring 9 surrounds the stem 7, at a point above the valve 8, and has its upper end abutting against the connecting portion of the sides of an inverted U-shaped frame 10, and has the lower end thereof resting on a plate 11, which rests upon the upper end of the valve 8 and is secured to the stem 7 in any suitable manner. The spring 9 serves to retain the valve 8 in normally closed position, and also to return the valve to closed position after the same has been released from open position. The upper end of the stem 7 extends through an opening in the connecting portion for the sides of the inverted U-shaped frame 10, and is slidable within the opening and has its upper end projecting a distance above the frame 10.

In use, the reservoir 1 is filled with a suitable poisonous liquid and when it is desired to destroy the life of a weed or other plant, the reservoir is moved downwardly in the direction of the ground so as to admit of the lower end of the stem 7 being inserted within the ground in the direction of the root of the plant. When the lower end of the stem comes in contact with the ground,

the stem 7 will be moved upwardly and unseat the valve 8, and establish communication between the reservoir and the nozzle, so as to admit of the liquid passing into the nozzle. The downward movement of the reservoir is continued until the lower end of the discharge spout is inserted within the ground. This insertion of the lower end of the discharge spout within the ground, prevents splashing of the liquid when being discharged from the lower end of the discharge spout and prevents the same from coming inicontact with the operator.

It is evidentthat various changes might be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of the invention as claimed:

prising, a body portion having its forward end portion screw threaded, a spout having an enlarged head adapted for threaded en 'gagement with said body portion, said spout being cylindrical an'd' of a iiniform diameter, a valve disposed at the inner end of said spout, an operating stem connected with said valve intermediate its ends and extending through said spout, a U-shaped frame connected to said body portion and having an opening for receiving said stem, and a coil spring interposed between said valve and the U-shaped frame.

In testimony whereof I afiix my signature in presence of two Witnesses.

JOHN GEHR'INGER.
